This application note provides step-by-step instructions on how to recreate a Tri-Mode Ethernet(TEMAC) performance testing system using the ML405 board and MontaVista Linux 4.0. Thisapplication note shows how to set up a simple EDK Base System Builder system on the ML405Evaluation Platform and run performance tests. The network architecture for the test isdescribed. A system is built and downloaded into the FPGA. A MontaVista Linux kernel isconfigured, built, and downloaded into the ML405 Evaluation Platform. The instructions forobtaining and setting up the software used to perform the measurements, netperf, are given.

The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct with minimal performance penalty. With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available fast GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary.

本軟件是關于MAX338, MAX339的英文數據手冊:MAX338, MAX339 8通道/雙4通道、低泄漏、CMOS模擬多路復用器 The MAX338/MAX339 are monolithic, CMOS analog multiplexers (muxes). The 8-channel MAX338 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. The dual, 4-channel MAX339 is designed to connect one of four inputs to a common output by control of a 2-bit binary address. Both devices can be used as either a mux or a demux. On-resistance is 400Ω max, and the devices conduct current equally well in both directions. These muxes feature extremely low off leakages (less than 20pA at +25°C), and extremely low on-channel leakages (less than 50pA at +25°C). The new design offers guaranteed low charge injection (1.5pC typ) and electrostatic discharge (ESD) protection greater than 2000V, per method 3015.7. These improved muxes are pin-compatible upgrades for the industry-standard DG508A and DG509A. For similar Maxim devices with lower leakage and charge injection but higher on-resistance, see the MAX328 and MAX329.

目錄執行摘要 01并購:中國下一個階段發展的主要增長戰略 03通過培養技能和積累經驗來克服困難 05在并購全程的三個階段實現最大價值 061. 制定成功的并購戰略:我們是在開展適當的交易嗎 062. 評估收購目標:不僅考慮經濟因素,而且還重點考慮業務模式與運行 093. 管理并監控整合工作:合并后的整合工作不到位常導致喪失大多數收益 11實現成功的并購:歸根結底依賴于適當的能力、人才和方法 15結語 16 并購:中國下一個階段發展的主要增長戰略參與并購活動的中國公司越來越多。2007年前11個月的交易量比2006年全年增長了18%,交易額增加了25%1。近期開展的調查顯示,每10家中國國內企業中就有9家稱他們參加過或者打算進行并購活動。2 然而,最顯著的趨勢是中國公司在最近的并購交易中更多是買家身份,無論是國內收購還是跨越國界的收購。相比之下,國外企業收購中國公司呈現下滑趨勢。多項國際調查顯示,許多并購都無法實現預期成效。然而也有證據表明頻繁參與并購的公司通過積累經驗而提高了成功率。本文涵蓋了IBM自己的經驗-如何使用和管理并購以便實現可持續增長,以及怎樣通過與領先公司合作來組織和管理并購。中國公司如能借鑒實用的洞察力和最佳業務實踐來克服挑戰,將會最大限度地提高并購全部三個階段的價值,最終受益匪淺。在并購活動中,中國公司日益成為收購方,而不是被收購方2006年,國內的并購占到中國總交易量的60%以上3(見圖1),主要驅動力來自政府或市場驅動的行業合并。中國政府一直都在穩定地合并大量國有企業以便打造更有競爭力的公司,特別是在電信、能源和交通運輸及資源等“戰略性”行業。這個趨勢在今后幾年中還將繼續發展,國務院國有資產監督管理委員會(SASAC)計劃到2008年底將國有企業的數量從2007年的155家減少至80-100家。4 在解除管制的行業,如零售、高科技和制造業,國內公司也掀起了一個合并浪潮,其目標是實現規模經濟并提高效率,從而在競爭日益激烈的市場中立于不敗之地。在中國發揮并購效力的法則謀事在人,成事在天?1H 2006 1H2007按類型對并購進行細分交易數量國內并購對內并購對外并購5 10 15 2016.3012.111.37.32.46.7600 400 200 05122582963161218交易額(單位:十億美元)圖1 按類型對并購進行細分資料來源:亞太區并購公告,2007,普華永道
